摘要

研究了一种基于超材料的双臂螺旋天线的辐射，其中双臂激励源的相位关系(偏差相位)发生了变化，导致了模式激励的不平衡。结果表明，当偏离相位达到约60度时，天线轴方向的辐射场减小了1 db。

Metamaterial-based spiral antenna with unbalanced excitation

The radiation from a metamaterial-based two-arm spiral antenna is investigated, where the phase relationship of the excitation sources for the two arms (deviation phase) is varied to cause unbalanced-mode excitation. It is found that the radiation field in the antenna-axis direction decreases by 1-dB when the deviation phase reaches approximately 60 degrees.
